SPECIFICATION formingpart of Letters Patent No. 716,408, dated December23, 02- Application filed October 18, 1902. Serial NO 1 (N0 model!)- Toall whom it may concern.-

Be it known that 1, WILLIAM S. GRAHAM, of the city of Canton, county ofFulton, and State of Illinois, have invented certain new and usefulImprovementsin Corn-Planters, of which the following is a specification.

This invention provides means for moving grains of corn horizon tallytoward the cells of aseed-wheel and for u ptilting the grains edgewiseinto the cells.

The invention is exemplified in the struc ture hereinafter described,and it is defined in the appended claims.

In the drawings forming part of this specification, Figure 1 is a planof a seedbox provided with my improvements. Fig. 2 is a plan of theseed-wheel. Fig. 3 is a plan of the under side of the feeder-disk. Fig.4 is a diagram showing fragments of the seed wheel and the feeder-diskand illustrating a modification of the embodiment of my invention shownin the other figures of the drawings. In Fig. 4 the feeder-disk is shownin horizontal section to expose the walls against which the extensionsonthe seed-wheel act while rocking the disk back and forth on theseed-wheel.

The ring of the casting to which the seedbox is attached is shown at 1,a cut-off housing is shown at 2, and a cut-off is shown at 3. Thecut-off housing has in this instance a lug through which a verticalpivot-pin 4 extends. A feeder-disk 5 is pivoted near its perimeter onpivot 4. Its perimeter is beveled, and it rests on the seed-wheel 6. Theseed-wheel has a set of seed-cells disposed in a circle concentric withthe center of the wheel, and it also has a pin 8 projecting. upward fromthe wheel to one side of the center thereof. The feeder-disk 5 has anelongated recess 7 in its under surface, the walls of which providebearing-surfaces for the pin 8 of the seedwheel and enable theseed-wheel to swing the disk or plate back and forth on pivot-pin at.

As the seed-wheel rotates the pin 8 strikes the walls of recess 7alternately and moves the plate from side to side of the seedbox, withthe result that the grains of corn are forced over the seed-cells andtilted thereinto.

In the modification shown in Fig. 4 there are three extensions on theseed-wheel, as shown at 8, and these act successively on opposite sidesof the oblong recess 7. This arrangement gives three oscillations of thefeeder-plate for each rotation of the seedwheel and insures feedingaction of the plate on all the cells of the wheel.

The feeder-plate has a horizontal motion to and from the cells and thebarrier-wall on the opposite side thereof, and it effectively forces thegrains over the cells and tilts them edgewise into the cells.

The lug 4 is merely suggestive of means for providing an eccentric pivotfor the feederplate, and it is obvious that such pivot may be providedin various ways.

The seed-wheel may be rotated in any desired manner, and the size,shape, and proportion of the various parts may be varied withoutdeparting from the principle of my invention.

The essential characteristic of this invention is the oscillation of afeeder-plate on the seedwvheel, so that the feeding part of the platewill alternately approach and recede from the cells, and it is obviousthat the oscillation may be accomplished in various ways.

I claim- 1. In dropping mechanism for corn'planters, the combination ofa seed-Wheel having cells disposed in a circle, a feeder-plate pivotedeccentric of the circle of cells, and means for oscillating thefeeder-plate on its pivot.

2. In dropping mechanism for corn-planters, the combination of aseed-wheel having cells disposed in a circle, a feeder-plate pivoted offits own center and off the center of the circle of cells and means foroscillating the feeder-plate 011 its pivot.

3. In dropping mechanism for corn-planters, the combination of aseed-wheel having cells disposed in a circle, a feeder-plate pivotedeccentric of the circle of cells, an extension on the seed disk off thecenter thereof and a wall in the feeder-plate against which theextension on the seed-wheel strikes to swing the feeder-plate on itspivot.

4. In dropping mechanism for corn-planplate back and forth as theseed-Wheel r0- ters, the combination of a seed-Wheel having tates. tocells disposed in a circle, a feeder-plate piv- In testimony whereof Isign my name in the oted eccentric of the circle of cells, aneXtenpresence of two subscribing witnesses.
